Objectives 6.1 To provide refined standards to assess carbon, water and nutrient budgets, and to develop the blueprint of an information system that combines a database with models and the possibility to run scenarios for plantations or sequestration ventures.   6.2 To develop a simplified methodology to assess carbon, water and nutrient budgets from the results of previous studies carried out in Eucalyptus plantations in the Congo.   6.3 To compare the accuracy of the estimations of carbon, water and nutrient budgets obtained with the proposed methodology and with reference methods.   6.4 To run scenarios on commercial Eucalyptus plantation in the Congo (on a 10,000 ha basis) to estimate the effects of forest management decisions (rotation length and type of harvest) on carbon sequestration as well as nutrient content in biomass removed at the harvest.

Description of work Task 6.1 Literature review.   Task 6.2 Assessment of carbon budgets.   Task 6.3 Assessment of nutrient budgets.   Task 6.4 Assessment of water budgets.   Task 6.5 Generalized model to predict C, H20 and Nutrient stocks and fluxes at the plot level.   Task 6.6 Coupling GIS and G & Y models.

Deliverables 6.1 A review report on method used to assess carbon, nutrient and water budgets (Month 12).   6.2 Publication of scientific papers in international journals (Month 18-36).   6.3 A book on the estimation of biomass and nutrient content in forest plantations (Month 24).   6.4 Refined standards to quantify carbon, nutrient and water budgets (Month 36).   6.5 Developed software that couples GIS and Growth and Yield model (Month 36).   6.6 Map carbon sequestration and nutrient cycling in standing biomass according to forest management scenarios (Month 36).

Milestones and expected result 6.1 Choice of the reference methods to quantify carbon, nutrient and water budgets (Month 12).   6.2 Preliminary standards to quantify carbon, nutrient and water budgets (Month 18).   6.3 Preliminary set of soil functioning indicators (Month 18).   6.4 Simulations of carbon sequestration and nutrient content in the standing biomass according to various forest management scenarios (Month 30).   6.5 Refined standards to quantify carbon, nutrient and water budgets (Month 36).   6.6 Consolidate the set of soil functioning indicators (Month 36).
